That's really interesting, Foolestroupe! THis site sheds more light on those "dark places" that intrigued the Incas:

Mathematics, Astronomy and Sacred Landscape in the Inkan Heartland

The animals in the sky were not patterns formed connecting stars, but black regions of the Milky Way (dark clouds of interstellar matter, from the astronomer's viewpoint) whose contours were identified with contours of animals [Bauer and Dearborn 1995]. Urton was able to identify unambiguously the following dark cloud constellations (Fig. 5):

   1. Serpent, between the star Adhara, in Canis Major, and the Southern Cross
   2. Toad, near Southern Cross
   3. Tinamou (partridge-like bird), "coal sack" below Southern Cross
   4. Llama, between Southern Cross and epsilon-Scorpio
   5. Baby Llama, "below" mother Llama
   6. Fox, between tail of Scorpio and Sagittarius
   7. a second Tinamou, in Scutum
